The MAX1510 DDR linear regulator sources and sinks up
to 3A peak (typ) using internal n-channel MOSFETs. This
linear regulator delivers an accurate 0.5V to 1.5V output
from a low-voltage power input (V
MAX1510 uses a separate 3.3V bias supply to power the
control circuitry and drive the internal n-channel
MOSFETs.
The MAX1510 provides current and thermal limits to
prevent damage to the linear regulator. Additionally,
the MAX1510 generates a power-good (PGOOD) signal
to indicate that the output is in regulation. During start-
up, PGOOD remains low until the output is in regulation
for 2ms (typ). The internal soft-start limits the input
surge current.
The MAX1510 powers the active-DDR termination bus
that requires a tracking input reference. The MAX1510
can also be used in low-power chipsets and graphics
processor cores that require dynamically adjustable
output voltages. The MAX1510 is available in a 10-pin
3mm x 3mm thin DFN package.
